It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I intend to fast; do you have anything (to eat or drink)?" He said: After Sayyiduna Bilal (may Allah be pleased with him) had called the adhan, I brought him (peace and blessings be upon him) a platter with dates in it and a vessel with water in it. He (peace and blessings be upon him) said: "Look for someone who will eat (with me)." So I went out and found Sayyiduna Zayd bin Thabit (may Allah be pleased with him). I called him, and he said: O Messenger of Allah, I have drunk a sip of sawiq (barley gruel), and I intend to fast. At this the Messenger of Allah (peace and blessings be upon him) said: "I too intend to fast." So he took the pre-dawn meal (suhur) with him (peace and blessings be upon him), then he (peace and blessings be upon him) prayed two rak'ahs, and after that he came out and the iqamah for the prayer was called.
